Structural Characteristics of Co Rotating Twin Screw Extruder

The screw and barrel of the co-rotating parallel twin-screw extruder adopt the advanced "building block" design. The screw is composed of various types of screw blocks set on the mandrel. The different blocks can be adjusted so that the ideal structure of the threaded element can be flexibly combined. According to the process requirements of the material type, various processes such as material transportation, plasticization, refinement, shearing, exhaust, decompression, and extrusion can be realized. The contradiction between the so-called versatility and specificity of the screw, which is generally difficult to be balanced, is better solved, and the purpose of one machine with multiple uses and one machine with multiple functions is achieved.


Ⅰ. Advanced control system of the co rotating twin screw extruder


The co-rotating parallel twin screw extruder is equipped with an advanced and beautiful control system. Most of its control components are imported components, which are of good quality and high sensitivity.


The operating parameters of the main machine of the co-rotating parallel dual screw extruder, such as current, voltage, temperature, torque, etc., are very intuitive, so it is very convenient to operate, and the requirements for operators are not high.


Accurate metering and reasonable feeding methods are the keys to strict formulas to ensure product quality. We are equipped with a variety of feeding methods according to the performance of the materials and the needs of users, such as volumetric measurement, dynamic weightlessness measurement, etc.


Ⅱ. Main screw configuration of the dual screw extruder


The main twin screws of the dual screw extruder are high-speed co-rotating intermeshing types, which can produce powerful and complex material transfer and exchange, split blending, and shear kneading in various threads and mixing elements.


These functions can be adjusted and controlled fully and freely by changing the screw configuration of the co-rotating parallel twin-screw extruder and the operating process conditions to meet the requirements of various processes.


The system of the co-rotating parallel dual screw extruder is equipped with several cutting methods such as drawing water-cooled pelletizing, hot-cutting water-cooling, and hot-cutting air-cooling. It can be configured according to different materials and user requirements.
